Five feet per second.
Seriously, it depends on a lot of different conditions. Smells travel in the air by what's called diffusion. Molecules are always moving, bumping and jostling each other, so they mix. The rate of natural mixing or diffusion depends on how often molecules encounter one another. The same with how long it takes a smell to dissipate. If the wind is blowing, there will be more mixing. That can either make the smell reach you sooner, or it can spread the smell out so that you don't notice it at all.
The speed with which a smell travels depends on how fast the molecules are going, how massive they are, the relative temperature of the molecules making the smell, and how many molecules there are in a given volume, their density. We express all this mathematically as a gas's temperature and pressure. By the way, our brains are quite used to air, so for the most part, we don't smell oxygen, nitrogen, or carbon dioxide; we smell the other molecules instead.

"Georgia" gave an excellent answer.
The speed at which an odor diffuses from its source depends on many factors including the temperature and what type of molecules make up the odor.
Lighter odor causing molcules (like gasses) will diffuse quicker than heavier (sold/liquid) odor molecules on average at the same temperature.
Remeber what "temperature" really means, it is the measurement of the average kinetic energy of the particles of a system, so if something has a high temperature, the particles have a high kinetic energy. Kinetic energy depends upon the velocity of the object (mass being held constant), so a higher temperature means that, on average, the particles are moving faster.

One interesting note, not all stinks travel at the same speed. For instance if you ingest corn, the speed of stink is relative to the foulness of the smell plus the velocity at which it was expelled. Now take Oatmeal, what it lacks in speed it makes up for in inertia, the stink of processed Oatmeal can punch a hole in denin.
The formula for speed of stink is written as follows.
fuel(this is the variable, re:corn vs. oatmeal) fuel will be represented by the letter "f"
Aperture of orifice the smell is expelled from will be repressented by the letter "a"
Rankness, or foulness of the smell will be repressented by the letter "R"
Total speed will be repressented by the letter "t"
this is the formula for F.A.R.T
F*A/R=T, I hope this helps.

well, the speed depends on the "air" it travels in, and the wind speed. However, since people cannot make a oder go a certain way, there is no definit answer

your question is rather dumb, but the speed of a smell is dependat upon air circulation, breeze, and Brownian motion. Look the rest up sir. Peace, Gizz

Faster than a speeding bullet, my sister used to pass gas, and the second we heard it we'd take off running cause we knew that stink would be to us in no time.

Too many factors to determine that...wind speed, air quality, strength of smell, up wind or down wind...
I think it would be near impossible to figure that one out.
But interesting thought.

that depends on the age of the farter(A) the height of the smeller(H) the Overall heath of the society(O) the length of time between meals (L) and the existence of previous odors (E)
therefore
Speed =(A-H)(OL)E
